If you install bash-completion before git or something else that creates
the bash_completion.d folder, the install of bash-completion itself
will fail. Commenting out until a proper fix can be made.
brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
Also fixes etc config.
The call to inreplace had an incorrect path. I tried correcting it
and leaving it as a post-make-install step, but it still did not work.
Moving the inreplace call did the trick.
